FIELD

This disclosure relates to the field of plant breeding. In particular,this disclosure relates to a new tomato (Solanum lycopersicum) varietydenominated ‘H1648’.

BACKGROUND

Breeding improved tomato varieties involves providing genetics that givean advantage to the grower, processor, consumer, or other members of thesupply chain. The improvement may be in the form of field performance,disease resistance, factory performance, or a fruit qualitycharacteristic. For a tomato variety to be suitable to be grown forprocessing, the variety must have a concentrated fruit setting andmaturity, firm fruit, and sufficient rot tolerance to allow early fruitto remain rot-free while later fruit continues to develop and ripen.

Most commercial processing tomato varieties are hybrids resulting from across pollination of two true-breeding, inbred parents. Through the useof true-breeding lines, a hybrid is produced that often displayscharacteristics of each parent, and often demonstrates characteristicsthat are superior to either parent alone, or that allow a hybrid to maskinadequacies of the individual parents.

DETAILED DESCRIPTION

Described herein is a new and distinct tomato variety named ‘H1648’ thatwas developed to provide a ground-culture hybrid tomato variety (i.e.,not grown on stakes) that is suitable for machine harvest, and isadaptable to the climactic conditions of regions such as California(USA), Ontario (Canada), Australia, Portugal, Spain, and Italy.

Processing tomato quality parameters differ from those of fruit used inthe fresh market. The processing characteristics are typicallydetermined using a sample of hot-break tomato pulp or juice produced ina consistent manner to those familiar with the art. For example, a fixedmass of tomatoes may be cooked in a microwave oven for several minutesto halt any enzymatic breakdown of the sample, lost water is replaced,and the sample is pulped to remove skins and seed to produce a uniformjuice sample. The juice sample can be analyzed for various qualityparameters important to processing tomato including but not limited togross viscosity measures such as juice Bostwick, soluble solids measuresusing a refractometer (ºBrix), measures of acidity and pH, and measuresof color (e.g. Hunter a/b score and levels of lycopene). The value ofthese traits depends on the product that is being commercially producedby the processing factory. In some instances, a factory will put ahigher value on a thick viscosity variety, whereas in other instances, athin viscosity will make a superior product and is preferred.

Processing tomato varieties combining resistance to verticillium wiltrace 1 (Verticillium dahlia), fusarium wilt race 1 and 2 (Fusariumoxysporum pv. lycopersici), and root knot nematode (Meloidogyneincognita) are highly desirable in most climates around the world.Varieties with tolerance to ripe fruit rots (extended field storage) arealso desirable because they are conducive to once-over machineharvesting, particularly in regions where rain can occur during harvestor there are delays in a harvesting schedule.

Moreover, in regions such as California, the industry has seen aconsiderable increase in pressure from two particular diseases: tomatospotted wilt virus (TSWV) and Fusarium oxysporum pv. lycopersici race 3(fusarium wilt race 3). Thus, varieties with resistance to either orboth are in high demand by both growers and processors to ensure aproductive crop cycle.

Processing tomato varieties that can produce high yields under intensepressure from bacterial diseases such as bacterial canker (Clavibactermichiganensis subsp. michiganensis) and bacterial spot, caused byvarious Xanthomonas species, are highly desirable in humid tomatoproduction regions around the world, such as Ohio, Michigan, and Brazil.

Moreover, an additional important contribution that tomatoes provide tothe human diet is the antioxidant lycopene. Specifically, processedtomato products are the primary source of tomato intake in the US dietand other countries around the world. Higher levels of lycopene arebeneficial both from a nutritional standpoint and from a consumerperception and quality standpoint. Tomato varieties having higher levelsof lycopene result in products with a deeper red color that can beconsidered an indicator of higher product quality. Thus, a tomatovariety with a higher level of lycopene and improved color in generalcan be valuable from a nutritional standpoint, a quality standpoint, anddesirability by the consumer. However, to be commercially viable, thetomato variety must perform acceptably in the field and factory asrequired by any other processing tomato variety. Often, varieties withenhanced lycopene suffer agronomic defects in yield, fruit firmness, orfield storage.

Described herein is a new and distinct tomato variety named ‘H1648’ thatwas developed to provide a ground-culture hybrid tomato variety (i.e.,not grown on stakes) that is suitable for machine or hand harvest, andis adaptable to humid climactic conditions of regions such as Michigan,Ohio, Indiana, Pennsylvania and southern Ontario Canada.

Plants of the tomato variety ‘H1648’ are resistant to verticillium wiltrace 1, fusarium wilt races 1 and 2, root knot nematode, bacterialspeck, bacterial spot and bacterial canker. Additionally, plants of thetomato variety ‘H1648’ have a vigorous upright vine compared to othertomato varieties of the same market class and very high yield potential.Fruit from the tomato variety ‘H1648’ is medium sized and has improvedcolor compared to other tomato varieties of the same market class.Moreover, the tomato variety ‘H1648’ is adapted to culture in both humidgrowing regions such as the eastern United States, southern OntarioCanada and humid European regions.

Stability of the Variety ‘H1648’

Variety ‘H1648’ is uniform and stable within commercially acceptablelimits. As is true with other tomato varieties, a small percentage ofvariants can occur within commercially acceptable limits for almost anycharacteristic during the course of repeated multiplication. However, novariants were observed during the two years in which the variety wasobserved to be uniform and stable.

Hybrid tomato variety ‘H1648’ has the following physiological,morphological, and other characteristics as set forth in Tables 1-4below.

Comparison of ‘H1648’ to Closest Varieties

Data in Table 1, 3, and 4 are based primarily upon trials conducted inCollegeville, Calif. (USA) from two replications, non-staked, in aresearch plot environment. Comparisons among varieties for processingtraits (Table 2) were done over two years of side-by side testingthroughout California. Disease resistance and adaptability assessmentsare based upon numerous observations collected throughout California andin regions/climates with specific disease pressure for ripe fruit rots,bacterial spot, bacterial canker, early blight, and late blight,including Ontario (Canada).

H1648 can be distinguished from H3402 and H9553 in that it has a morevigorous vine with darker foliage, old gold crimson flower color, andlarger fruit with improved internal color. H1648 represents asignificant soluble solids (° Brix) advantage compared to industrystandard varieties H3402 and H9553. Disease resistance in H1648 issuperior to H3402, providing higher levels of resistance to bacterialcanker and bacterial spot. In addition, H1648 is resistant to bacterialspeck compared with susceptible variety H9553.

Further Embodiments

Additional methods include, without limitation, chasing selfs. Chasingselfs involves identifying inbred plants among tomato plants that havebeen grown from hybrid tomato seed. Once the seed is planted, the inbredplants may be identified and selected due to their decreased vigorrelative to the hybrid plants that grow from the hybrid seed. Bylocating the inbred plants, isolating them from the rest of the plants,and self-pollinating them (i.e., “chasing selfs”), a breeder can obtainan inbred line that is identical to an inbred parent used to produce thehybrid. Accordingly, another aspect of the disclosure relates a methodfor producing an inbred tomato variety by: planting seed of the tomatovariety ‘H1648’; growing plants from the seed; identifying one or moreinbred tomato plants; controlling pollination in a manner whichpreserves homozygosity of the one or more inbred plants; and harvestingresultant seed from the one or more inbred plants. The step ofidentifying the one or more inbred tomato plants may further includeidentifying plants with decreased vigor, i.e., plants that appear lessrobust than plants of the tomato variety ‘H1648’. Tomato plants capableof expressing substantially all of the physiological and morphologicalcharacteristics of the parental inbred lines of tomato variety ‘H1648’include tomato plants obtained by chasing selfs from seed of tomatovariety ‘H1648’.

One of ordinary skill in the art will recognize that once a breeder hasobtained inbred tomato plants by chasing selfs from seed of tomatovariety ‘H1648’, the breeder can then produce new inbred plants such asby sib-pollinating, or by crossing one of the identified inbred tomatoplant with a plant of the tomato variety ‘H1648’.

The disclosure further includes introducing one or more desired traitsinto the tomato variety ‘H1648’. For example, the desired trait mayinclude male sterility, male fertility, herbicide resistance, insectresistance, disease resistance, and drought resistance.

The desired trait may be found on a single gene or combination of genes.The desired trait may be a genetic locus that is a dominant or recessiveallele. The genetic locus may be a naturally occurring tomato geneintroduced into the genome of a parent of the variety by backcrossing, anatural or induced mutation, or a transgene introduced through genetictransformation techniques. For a genetic locus introduced throughtransformation, the genetic locus may comprise one or more transgenesintegrated at a single chromosomal location. Accordingly, the disclosureprovides tomato plants or parts thereof that have been transformed withone or more transgenes (i.e., a genetic locus comprising a sequenceintroduced into the genome of a tomato plant by transformation) toprovide a desired trait. In one aspect, the one or more transgenes areoperably linked to at least one regulatory element.

The gene(s) may be introduced to tomato variety ‘H1648’ through avariety of well-known techniques, including for example, molecularbiological, other genetic engineering, or plant breeding techniques,such as recurrent selection, backcrossing, pedigree breeding, molecularmarker (Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), and Simple SequenceRepeats (SSRs) (also referred to as Microsatellites)), enhancedselection, genetic marker enhanced selection, and transformation.Accordingly, tomato seed, plants, and parts thereof produced by suchgenetic engineering or plant breed techniques are also part of thepresent disclosure.

Also provided herein are single locus converted plants and seedsdeveloped by backcrossing wherein essentially all of the morphologicaland physiological characteristics of an inbred are recovered in additionto the characteristics conferred by the single locus transferred intothe inbred via the backcrossing technique. A single locus may compriseone gene, or in the case of transgenic plants, one or more transgenesintegrated into the host genome at a single site (locus). One or morelocus conversion traits may be introduced into a single tomato variety.
